From MC's perspective:
After recovering my strength, I appeared outside. Without wasting time, I appeared before the black hole and pointed my fingers at the ground hole to cast the magic spell.
"Gravity Blast," I cast the magic spell.
In the next second, a wisp of gravity magic is released from the finger and reaches the target in a blink of an eye.
Boom~
The gravity magic explodes right after coming into contact with the hole.
Rumble~
The next second, the ground beneath me starts to shake. I saw the whole land shaking in front of me as some earthquake had occurred.
Swoosh~
Before something unknown happens, once again I appeared in the Gregor mansion. When I entered the control room to see the changes.
A hint of disbelief flashes in my eyes.
Finally, I spotted the appearance of the monster.
